About Me

Hi, I'm Alexander, an Informatics graduate with a passion for turning ideas into meaningful software. I enjoy building full-stack applications that solve real-world problems, from designing intuitive user experiences to developing reliable backend systems. I'm driven by curiosity, continuous learning, and the satisfaction of creating technology that makes people's work easier and more efficient.

Beyond software development, I'm particularly interested in software architecture, cybersecurity, and building systems that are scalable, maintainable, and secure. Outside of coding, I enjoy cooking, traveling, and gaming — interests that keep me creative, curious, and always eager to learn something new.
